A cloud platform supports an object preview service. A user may configure a data object preview, and the object preview service stores a set of instructions for the data object in a preview library. The object preview is associated with a unique identifier, which is associated with an identifier of the preview library. The object preview service may receive requests from client systems, and the request may indicate a data object. The object preview service identifies the set of instructions based on user interface (UI) configurations of the client system and the request. The object preview service transmits the instructions to the client system, which outputs the data object preview at a UI according to the instructions.
